That was never a good PvP build. For PvE there are better options but it is fine for a lot of content.

And to tie it up I completed hardmode imperial city prison first try in a random group. So it's fine

It’s not bad, but I bet you don’t get much damage out of the fire side of Ilambris. Maybe not too bad if you use an Infused Flame enchant. You could try Zaan (for close range) or Slimecraw (if you don’t have combat prayer).

The other option would be build around Ilambris by adding some fire damage, in which case you would want to drop Netch for something like Mother’s Sorrow (that applies to all damage types).

Not that your current build isn’t viable for vet content, it should get you through any content fine, just not fully optimized.
